Akinetic seizures
What is Akinetic Seizure?
An akinetic seizure is a type of seizure involving just a brief period of lack of movement, usually lasting less than a minute. Akinetic seizures typically occur in patients with medial temporal lobe epilepsy or frontal lobe epilepsy. These seizures are often preceded by a brief warning sensation.
During akinetic seizures, the patient may appear alert and conscious, but will exhibit a sudden stop of movement for a short period of time. Akinetic seizures are usually of a very brief duration and can range from seconds to a few minutes. These seizures are typically characterized by a sudden cessation or slowing of ongoing activity, although some patients may have tonic-clonic movements of the limbs.
Symptoms of Akinetic Seizure
Akinetic seizures can vary in severity and symptoms, but common signs include:
- A brief period of lack of movement or an inability to start an action
- Loss of muscle tone
- Lips may become dry and curled
- Brief period of unconsciousness, usually lasting less than a minute
- May have tonic-clonic movements of the limbs
Treatment for Akinetic Seizures
Treatment of akinetic seizures typically involves controlling seizures with antiepileptic drugs (AEDs). Typical AEDs used to treat akinetic seizures include carbamazepine, lamotrigine, levetiracetam, and topiramate. Seizures that are only partially controlled by AEDs can often be treated with surgery.
In addition to the use of AEDs, patients with akinetic seizures should be observed closely and monitored for any changes in seizure activity or development of comorbidities. Close observation is also recommended for younger patients, as cognitive development can be affected if seizures are frequent.
